Could 'The Flash' movie be as dark as 'Seven'?

With "Green Lantern" already in post-production, DC Entertainment and Warner Bros. appear to be ramping up development of the long awaited big screen incarnation of "The Flash." The super speedster's screenplay is being written by Michael Guggenheim, Michael Green and Greg Berlanti and Guggenheim made some key revelations to MTV about their work so far. Most intriguing is that the hero's alter ego, Barry Allen, will now be a forensic scientist a la "C.S.I." and the film will have a dark and grittier tone than you'd expect. Guggenheim says, "The tone is sort of darker, and more like "Seven" and "Silence of the Lambs" in that mysterious and noir-ish way, which is also working in conjunction with the superhero elements. It's a lot of fun. I think the character is made for a story and a screenplay that gives you more than the sum of its parts."

The writer also revealed the film will have more than just a crime thriller theme to it. He notes, "There's also an element of a sports movie, because the character is so physical and I feel like there is an athleticism to his power that other superheroes don’t have. I think that's pretty cool."

No word on who would star or direct in a big screen version of "The Flash."
